This is not the easiest species to correctly identify as it has been suggested that S. koensis and S. tourei are very similar to each other. The 4th, 5th and 6th thumbnails match the Holotype of S. koensis from Poll, (1971) but the adipose fin is larger in this specimen so they may turn out to be hybrids instead. Description: Dorsal spines (total): 1; Anal spines: 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; post-orbital length at least 60% of snout length; maxillary barbels longer than head, unbranched, without tubercles, but bordered by a narrow, black, hardly visible, basal membrane; outer mandibular barbels with numerous, rather long, simple and thin ramifications; branches of inner mandibular barbels shorter, subdivided and partly tuberculate; mandibular teeth rather short, numbering 37-47; denticulations of pectoral-fin spines weaker on outer than on inner margins; dorsal-fin spine smooth anteriorly and weakly denticulate posteriorly; humeral process blunt, at most about twice as long as deep, its upper margin more or less convex; adipose fin rather poorly developed and distinctly separated from rayed dorsal fin; body covered with irregular, more or less coalesced spots. Colouration: Rather dark, lighter ventrally; body entirely covered with brownish spots and marblings against a lighter background; spots on ventral body regions also large, but lighter; all fins marked with spots aligned in transverse series; adipose fin of the same colour as rest of body; top of head also spotted. Remarks: Reported to be unproblomatic in captivity.
